Hi Evan,

I'm not sure, I find a lot of these:

2013-03-30 23:27:52.992 [error] 
<0.8036.323>@riak_api_pb_server:handle_info:141 Unrecognized message 
{22243034,{error,timeout}}

and some of these at the same time one of the kind below gets logged 
(although the one has a different time stamp):

2013-03-30 23:27:53.056 [error] <0.9457.323>@riak_kv_console:status:178 
Status failed error:terminated
